Ultra HD in deep focus

Ultra HD in deep focus

A traditional three-sensor 2/3-inch camera is Ikegami’s new entrant to the Ultra HD production stakes. The Unicam UHD camera uses 4K-native 8-megapixel CMOS chips and traditional prism optics to provide the deep focus favoured for broadcast operation, particularly for sports.

It is designed for easy integration into studio and OB truck systems, with the same ergonomic and operational features as a conventional Unicam HD camera. A 2/3-inch B4-mount allows direct docking with conventional lenses plus a focus-assist function, while uncompressed RGB 4:4:4 baseband is delivered from the camera head to the newly designed 4K-UHD base station to ensure the highest possible transmission quality.

Also new is Ikegami’s BS-98/CCU-980 hybrid 2K/4K, rack-mountable optical-fibre transmission link. It is being demonstrated, alongside new UHD displays, delivering HD and 4K processed UHD signals simultaneously, so that users can employ existing HD cameras and accessories, including lenses, for 4K productions as economical bridge equipment.

A new robotic camera system based on a combination of the Ikegami HDL-45E head mounted on a pan/tilt unit, both controlled via an Ikegami iHTR-100 fibre-optic transmission link, is also on show. The multi-purpose HD camera has three 2/3-inch 2.3 megapixel AIT CCD imagers, an LSI processor and 14-bit A/D converters and can be used in lighting levels down to 0.065 lux without frame accumulation, or 0.00054 lux with frame accumulation. The iHTR-100 link operates at distances of up to 10km and can multiplex up to 20Gbps of multiple format video with very low delay.
